Is there an alternative / plugin for Visual Studio's configuration manager?

I have the need to remove and rename a selection of solution/project configurations in visual studio, are there any tool which will help with this?

I'm finding the built in tool very unhelpful. For example, when I delete a configuration from a solution it will refuse to delete the related project configurations just in case they are needed elsewhere. Also renaming a solution configuration will not rename it's related configurations.

There must be a better way of doing this. Any alternative tools out there?
